According to Nguyen Van Huong, Head of Climate Forecasting Department (National Center for Hydro-Meteorological Forecasting), around March 31 to April 1, a strong northeast monsoon will move into the water again. ta.

Due to the influence of this northeast monsoon, in the 2 days of March 31 and April 1, the North and North Central regions experienced showers and thunderstorms in a large area, in the mountains of Viet Bac and the Northeast, there were places where they appeared. moderate rain, heavy rain and strong thunderstorm, in a thunderstorm can occur storms, whirlwinds, hail and strong gusts of wind.

From the night of March 31, the temperature dropped sharply, in the North and North Central, it turned cold with the lowest temperature in the North about 14-17 degrees, in the mountains below 13 degrees, in the North Central region, the temperature was low. about 1-2 degrees higher than the northern part. “Although the level of cold is not deep, but because it is March of the lunar calendar, it can be said that this is Nang Ban cold in the late winter-spring period of this year”, Mr. Huong shared.

Before catching this strong cold air, in the days from March 28-31, the northern provinces maintained cloudy weather, with fog in the morning, night and morning, it was cold with the lowest temperature common at 18. -21 degrees, highest temperature 26-28 degrees.

Mr. Nguyen Van Huong, Head of Climate Forecasting Department of the National Center for Hydro-Meteorological Forecasting.

A representative of the National Center for Hydro-Meteorological Forecasting recommends that the end of March and April is the time of season change. Therefore, although the intensity of cold air is no longer as strong and continuous as during the main winter period, usually, before the cold air penetrates down, the temperature is quite high, so there will be a dispute between the two. Air masses are of opposite nature, causing great instability in the atmosphere.

“Therefore, the risk of extreme weather events such as storms, whirlwinds, hail and strong winds during thunderstorms is very high, especially in mountainous provinces,” Mr. Huong said.

According to the Center’s forecast, in April this year, the cold air is more active at the same time every year, so the temperature in the Northern provinces is about 0.5-1.5 degrees lower than the average for many years, in some places. up to 2 degrees lower.

“Besides, April is the time when the western low pressure area also gradually develops to the east, although it is not strong, it also causes disturbances in the atmosphere every time the cold air moves down. Chances of storms, tornadoes, hail and strong winds are at a high level”, Mr. Huong shared.
